This invention relates to an adjustable chiropractic bed appliancewhereby the spring is taken out of the bed mattress so that achiropractic adjustment can be given to a patient without removal fromthe bed.

rin object ot my invention is to provide an applianceotl the characterstated which can readily be transported and which can li@ quiclily andeasily placed in position.

A further object is to provide a chiropractic bed appliance which isreadily adjustable to accommodate various beds.

Still another object is to provide an vappliance ot the character statedwhich is simple in construction, ellective in use, and inexpensive tomanufacture.

' ther objects, advantages, and features of invention may appear fromthe accompanying drawing, the' subjoined detailed description, and theappended claim.

In the drawingl Figure lis a side elevation ot a bed with my appliancein positionthereunder.

Figure 2 is an end view of the same.

Figure 3 is a fragmentary sectional view olE one of the locking members.

f Figure -l is a sectional view taken on line ll, /l ot vFigure 8.

Figure 5 is a. side elevation ot one of my appliances.

Figure 6 is an end view ot' the same.

Referring more particularly to the drawing. the bed 1 is provided withthe usual mattress 9. upon which the patient lies and as previouslystated it is necessary to prevent the action of the springs under themattress so that an adjustment can be given Vto the patient. Iaccomplish this by means oi a pair of adjustable and yet rigidappliai'icc.' 3,' each ot' which comprises a pair or" l 4, 5, said legsbeing preferably ol chan .el

iron construction, although, obviously, any

suitable strong construction could be used.

A tube 6 is secured to one end of the leg 5 and rises substantially atright angles therew i to, said tube being welded. or otherwise suitablysecured to the leg. A post 7 is secured kto one end or" the leg 4 in thesame manner as the tube 6 and this post extends substantially at rightangles tothe leg t.v The post 7 lits closely within the tube and isslidable therein.

'l`hc post is held at various adjusted positions by means ot a lockingpin 8 which extends into the side ol' the tube t3, and a spring 9 beursagainst the heL 'l l() to urge said head inwardly into one of a seriesof notches 11 in the post 7. A square recess is provided in the post 7and when the pin 8 c' ers this recess the post is in collapsed po- ,nand will not move outwardly until said pin is released. Duringtransportation 'from place to place the pin rests in the recess 12 and,theretore, the two legs 4, 5 cannot be accidentally spread apart. Toprevent rotation ot the legs fl, 5 I provide a key 13 in the tube 6which liey lits into a slot 14 in the post 7.

In operation, the two appliances 3 are pushed under the bed, the upperleg l resting inuncdiately under the mattress 2. The legs a?, 5 arepulled aparta suflicient distance so that the mattress will not restupon or receive any resiliency from the springs ot the bed. Theappliances 3, 3 are spaced a suitable distance apart under the mattressand the patient is then moved on the mattress until he restsinnnediately over the appliances 3, 8 and bears upon the upper leg` fl.The practitioner can now readily complete the ad pistment.

Having described my invention, I claim:

An adjustable chiropractic bed appliance adapted to bepositioned under abed having springs, whereby the resiliency is taken out of the springs,said appliance compf'i .g a horizontally extending leg formed of channeliron, a tube rising from one end ot said a second leg formed of channeliron, a post depending from one end of said second said post extendinginto the tube, said post and tube having' key-ways Jformed therein, akey in said hey-ways whereby relative rotation ot said post and tube isprevented. a springl actuated pin extending through said tube.v saidpost having recesses therein into which the pin extends whereby the postis arl-justably held in the tube.

Iu testimony whereof. I my signature.
